Top 5 Benefits From Plastic Injection Molding

Plastic injection molding has become one of the fastest and least expensive ways to produce large quantities of plastic parts. It's used worldwide for fabrication of plastic parts. This process has many benefits that should be considered before using it - and we are naming top 5 benefits that separates plastic injection molding from other manufacturing processes.


Speed and precision
Using plastic injection molding in the manufacturing process is a fast and safe way to produce large quantities of plastic parts in relatively short period of time. For instance, it usually takes 15 to 30 seconds between two production cycles, so in an 8-hour work day you have 90 production cycles. However, this number can vary depending on the size and the complexity of the mold itself or the material used.

The other great benefit that comes from plastic injection molding process is precision regardless of the type of the material or the design of the mold used. It can fabricate almost every type of plastic parts.


Resourcefulness
The sustainability is a major issue among manufacturers today, so it's very important to choose a process that wouldn't have a significant impact on the environment. With the plastic injection molding process, manufacturers are assured that it won't affect the environment and especially it will minimize the amount of waste.

On the other hand, the resourcefulness of the plastic injection molding process is mirrored in two crucial outcomes:
1. it's always used the exact amount of the material (which minimizes the waste) and 2. if there's a waste, it can be recycled and used again without jeopardizing the quality of the product.


Low scrap rates
The traditional manufacturing processes cut away a significant percentage of the material (which is packed as a block or sheet). That way, the scarp rates are much higher and the amount of waste material after the process can only indicate higher manufacturing costs for traditional manufacturing processes.

However, the waste from plastic injection molding typically comes from four sources: the sprue, the runners, the gate locations and any overflow of the material that leaks out of the part cavity itself. In comparison to the traditional manufacturing process, the amount of waste can be controlled and predicted so that the total scrap rate wouldn't exceed the lowest threshold.



Low labor costs
One of the greatest benefits of this manufacturing process is that it is extremely scalable, meaning that it doesn't require a large workforce in order to produce on a high-level quantities each day. With just one plastic molding machine you can achieve significant production rate without having the pressure to hire actual human workforce to conduct the manufacturing process. That way the costs of the production are reduced. However, it should be noted that the actual cost of the machines is high, which can be taken as a downside of the plastic molding process.


Ideal for creating high-strength components
Plastic injection molding can be applied to almost every type of plastic related production that is known and used in variety of different industries. Thus it's a flexible process which enables you to adjust the strength of the final product during the process itself. It's an ideal solution for creating some high-strength components because it doesn't require to start the process from the beginning.
